Compact Track Loader
12. Undercarriage Disassembly and Assembly
12-4
NOTE: Bearings
In the illustration above, the rear wheel is shown
with a tapered roller style bearing while the center
wheel is shown with a ball type bearing. It is
important to note that these bearings are positioned
within the undercarriage as they are, in order to
adequately bear the differing loads/forces applied to
them.
When replacing bearings or removing wheels,
always make sure the front and rearmost wheels
in the undercarriage are equipped with tapered
“roller” type bearings, while the eight interior
wheels are to be equipped with “ball” type
bearings. They are not interchangeable in this
application.

4. Pry the drive table assembly upward, away from
the tensioner. Then pivot the tensioner forward

lower the drive table until it rests on the rail.
